restoring and other data
why can't I restore my iphone? My "other" data is taking up 5GB of my 6.34 capacity storage. Have erased all photos, videos, apps and music. when i try to restore I get a message that: could not restore, the device isn't eligible for the requested build. Anyone have any suggestions to: a) get the other data off my phone, b) restore phone?!!??!
Any advice appreciated.
iPhone 4 (8GB)
